RS-232 Maximum Cable Length
The maximum cable length for RS-232 is 50ft, but in practise depends on baud rate, cable specific capacitance and ambient noise. The table below contains some rules-of-thumb from experiments done by Texas Instruments years ago.
|Baud rate||Maximum range / cable length|
- Voltage: +5V
- 16 digital IO port (including a I2C interface)
- 6 analog IO port and power
- Operation and programming mode switch
- Transceiver indicating LED
- DB9 connectors (female), RS232 pins
- Weldable area
- Reset switch
- Module size: 55mmx53mm (2.16"x2.08")
